Rarely will a band test the possibility that if one lead singer is good, more might be better. Divas on Fire does.

In this band, divas outnumber players by a margin of 6-4. One some songs, the singers pass the lead from one to the next. On others, one voice prevails while the others form a massive backup squad.

The all-woman band from Fayetteville, Arkansas, will co-headline the Greater Ozarks Blues Festival, today and Saturday at American Legion Vietnam War Memorial Post 639. The event has a strong lineup of numerous local bands, which, heard one after another, will demonstrate the depth of blues talent in the area. The Saturday session will culminate with another northwest Arkansas unit, Earl and Them, led by the dynamic guitarist Earl Cate, followed by the Divas.

Divas on Fire singer Lectric Liz described the band’s sound in ways that live up to the “fire” part of its name: “Definitely rock-based blues, R&B and gospel. Rock in the sense that our sound is fat and full and pretty much in your face.”

However, the “diva” aspect is tempered by the divas’ willingness to share the spotlight. The six vocalists all are lead singers in their individual bands, and they relish the opportunity to sing backup parts in Divas on Fire, Liz said.

“The thing that I enjoy is watching the crowd when we start belting those backups on songs like ‘Hold on I’m Comin’ ’ and ‘With a Little Help from Our Friends,’ ” Liz said. “People’s eyes get wide, their mouths drop open, and they stand there like, yeah! It’s fun.”

A quartet of guitar, keys, drums and bass drive the band, with keyboard presets that enlarge the sound to include horns and other effects, she said.

Brenda Seely, president of the Blues Society of the Ozarks, said she booked the Divas based on hearing the band last year. “I was blown away. We’re very lucky,” Seely said.

BSO has emerged from a couple of weather-distressed festivals, which diminished the organization’s coffers. Last year’s event was a success, enabling BSO to hire first-rate regional talent along with local bands.

At sundown today, Post 639 and BSO will present a Ceremony to Remember 9/11, including a police honor guard, flag ceremony, Pledge of Allegiance, gun salute, bagpipes and taps.

Planners are aiming to present a free event next year, the 20th anniversary festival. That depends on the outcome of this weekend’s festival and success in recruiting additional sponsors, Seely said.

Ozarks Celebration Festival

Missouri State University’s annual heritage event, Friday-Sunday, will include a free encore performance of the Hillbenders’ “Tommy: A Bluegrass Opry,” a stunning reinterpretation of the Who’s rock opera. If you missed this show back in May at Patton Alley Pub, here’s another chance.

The show will be part of Friday evening’s Ice Cream Social & Concert Under the Stars, with festivities starting at 5:30 p.m.. The concert will include the Blackberry Winter Band, purveyors of traditional Ozarks music featured in the film “Winter’s Bone.”
